Abstract
Against the dualistic conception of mind and matter that is characteristic of much modern philosophy, ancient philosophers (Aristotle and Sophocles) show us that our powers are always embedded in nature, and the existence of those powers is dependent upon the existence of the bodies they are “of” Aristotle’s discussion of the habituation in particular offers us the chance to see the materialityand the labor that are presupposed in the acquisition of new powers. Thucydides, finally, shows us the care needed to maintain the existence of these powers, and equally the attitude of neglect that the possession of these powers naturally induces.
